Margin calls by those who lost on CLSN I would expect will require some selling, that and feeling nervousness with another bio tech play.
Overconfidence can lead to over-betting, results are never guaranteed.
I doubt CTIX would have broken support otherwise, and probably would have already hit new highs if a lot of money and attention hadn't shifted to the other play.
At least the focus can now return to CTIX where the fundamentals remain strong.
